' l .application led'lltay 6,

T 0 all whom t may concern:

Beit known that l, CHESTER H. BEACH, .a citizen of the United States,residing at Racine, in the county of Racine and State of l/Visconsin,have invented certain new and -useful improvements in Drink Mixers, of

which the following is a specification.

'My invention relates to improvements in drink mixers such as are usedat soda fountains. I

rlFhe object of the invention is to provide 'improved means forsustaining the weight of the motor and to provide a drink mixer ofgenerally improved construction.

lin the accompanying drawings l have illustrated one embodiment of theinvention, in which- Figure 1 is a side elevation of the device partlyin section; I r i Eig. 2 is a section on the line 2-2'of Fig. 1; y

Eig'. 3 is a sect-ion on the line 3'-3 of lFig. 1; and

Fg. t is' a rear elevation of part of the device.

The structure comprises a base 1, which is preferably in the form of acasting with an upper surface of vitreous enamel to improve itsappearance. A pedestal 2 is supported on said base, and ,is providedwith a channel or groove 3`on each side, forming ways or guides to guidethe up vand downmovement 'of the channel-shaped member 4C which supportsthe motor. The lower end of said channel member is provided with a pairof narrow plates 5 suitably secured thereto, as by screws 6, the inneredges of said vplates sliding within the grooves 3 and servin to lockthe upper and' lower members o the supporting structure together, inaddition to guiding the upper member in its movement. Y

'lhe upper end ofthe channel member has a small electric motor 7 securedthereto with its armature shaft in vertical position, a spindle orextension 8 being secured thereto, carryin a head or agitator 9 at itslower end. uitable conductors, encased in Hexible armor 10, connect themotor with a supplycircuit, a switch 11 being also provided mounted inconvenient position ona block `of insulation 12, which is, in turn,supported on a metal bracket 13 secured to the upper end of' the channelmember 4. The lower 1921. Serial N0. 467,266.

' end 14: of the bracket is turned outwardly and engages a resilientbuffer 15 when the motor 1s moved to lowermost position. A plate 16 isheld in position by a small bolt .17, the head of which carries thebuffer 15. Said plate 'prevents the operator from lifting the channelmember et so high as to disengage it from the pedestal 2.

The motor is sustained in uppermost position by means of a cord 18secured in a slit in the lower end of the channel member and `passingover a pulley 19 mounted in a suit able recess in the upper front faceof the pedestal. Said cord passes down through an opening in the castingand over a second pulley 20 mounted on the base 1, and then passesaround the periphery of a larger pulley 21. rll`his-largerzpulley has a.series of holes 22, into any one of lwhich a small hook 23, on the endof the cord, may be hooked. Said pulley is mounted on a stud 24, with acoiled spring surrounding said stud and having one vend extendingthrough an opening in said pulley and the other end projecting into anopening in the base plate 1. The spring is so tensioned as to balancethe weight of the moto-r and its associated parts, whereby the motorwill remain in any position vertically to which it may be moved eitherup or down. 'llhe lass or `other receptacle is placed within t e usualspring clips 26'mounted on the base.

'llhe construction described does away with the necessity of telescopingupper and lowermembers, such as have been used here- Y tofore, withinwhich a spring has been mounted to sust-ain the weight ofthe motor. llnsuch a prior device a fairly long spring is required, whereas in thepresent case a rsmall spring serves the purpose and may be so tensionedas'tosupport the motor in any desired position. 'llhe friction is suchthat it is not necessary to provide a locking device'to hold the motordown while the agitator is stirring the liquid in the receptac e.

l .claim:- 1. A. drink mlXer compr1s1ng a base, an

upright support thereon, a motor having sliding engagement with saidsupportfan agitator driven by said motor, and means mounted within saidbase for sustaining the weight' of said motor.

` 2.` A drink mixer comprising a hollow base, a pedestal thereon, asupporting member having sliding engagement with said pedestal, a motorcarried by said supporting vmember, an agitator driven b-y said motor,

of movement of said end and downwardly into said base, and a membermovable in a horizontal plane to which said cord is secured and impelledby a spring in a direction to counteract the weight of said motor.

4. A drink lmixer comprising a base, a pedestal thereon, a member havingsliding engagement with said pedestal, a motor ,mounted on said member,a cord secured near the lower end of said member and extending over asupport above the upper limit of movement of said end and downwardlyinto said base, a pulley mounted on said base to turn about a verticalaxis, and a coiled spring surrounding said axis and secured to saidpulley, the lovveri end of said cord passing around said pulley andsecured thereto. i

5. A motor having an agitator rod depending therefrom in verticalposition, a channel member to which said motoris secured, a verticalpedestal, means providing a sliding connection for said channel memberon said pedestal, a hollow base supporting said pedestal, a horizontalpulley mounted within said base, a coiled spring secured to said pulleyand base, and a cord extending around the rim of said pulley andpassingl upwardly through. said pedestal to said channel member tosupport the weight of said member and of said motor.

6. A drink mixer comprisin a hollow base casting, a vertical stud withlnthe same, a pulley mounted on said stud, a coiled spring surroundingsaid stud and secured to said base and said pulley, a pedestal mountedon said base and having a vertical recess therethrough communicatingwith the space in said base, a small pulley mounted beneath said recess,and a second small pulley at the upper end of said recess in saidpedestal, a cord passing around said irst pulley and over two smallerpulleys, a vertical member having sliding engagement with said pedestal,said cord being secured to the lower end of said member, and an electricmotor securedto the upper end of said member.

7. A drink mixer comprising a motor, conductors extending therefrom, avertical support for said motor, a switch mounted on said support andinterrupting said conductors, a pedestal having channels therein,extensions on said support sliding in said channels, a spring-controlledpulley beneath saidpedestal, and a cord connecting said member andpulley to balance the weight of the motor and its associated parts.

8. The combination with a'drink mixer comprising a motor having adepending agitator and a supporting base, of means in said base forsustaining said motor, comprising a pulley having openings near itsgroove and a flexible member lying in said groove with a hook at its endcaught in one of said openings and maintained under tension by theweight of said motor.

In testimony whereof, I have subscribed my name.
